How Long Do Helium-Filled Latex Balloons Last?

If you’re planning a party with balloons, timing is everything. A common question is: how long do helium-filled latex balloons last before they deflate?

Average Floating Time

On average, standard 9-inch to 12-inch latex balloons filled with helium last about 8–12 hours. After this time, they begin to shrink and lose buoyancy.

Factors That Affect Balloon Lifespan

• Balloon Size: Larger balloons hold helium longer (up to 24 hours).
• Temperature: Hot or cold conditions can shorten float time.
• Balloon Treatment: Using special balloon sealants (like Hi-Float) can extend float time up to several days.

Pro Tip

If your party is in the evening, inflate balloons on the same day for the best results.
